The prototypes for scalbf and scalbl given in scalb.3 are incorrect.
If you have doubts, try compiling the following code:
#include <math.h>
double scalb(double x, double exp);
float scalbf(float x, double exp);
long double scalbl(long double x, double exp);
To gain confidence that the prototypes below are correct, compile the
following:
#include <math.h>
double scalb(double x, double exp);
float scalbf(float x, float exp);
long double scalbl(long double x, long double exp);
Or search for man pages from other sources, e.g.:
http://www.unix.com/man-page/OpenSolaris/3m/scalbf/
http://docs.oracle.com/cd/E26505_01/html/816-5172/scalb-3m.html
The patch below fixes these mistakes.
Thanks,
Mark
